Tomorrow going to my offshore-schedule! BUT today there for the first time was (and is) sound through this little beast; and what a sound. So fullbody and rich in tonal spectrum. Did not expect that it would be so much better than my ClassDaudio amplifier - but it really shines and fills the room. I have to turn my B1 up to about 40 % to keep the same level as on the ClassD(but that was expected).

I have a couple of unfinished issues still(the big hole you see, as this was originally boxes intended for 3liter wine, that I rebuilt to fit.)

But for now - perfect. May try some other solutions later, but with 12,5 ohm filmresistor and 400 watt on them - and 400 watt/2x35 volt ACtrafo on each monoblock, there is nothing missing.
For the moment......

Still missing some parts to start building my SIT, I was thinking to try the following output changes. Can we avoid the mid and Super tweet caps if I change the signal polarity trough my pre and connect SIT (-) to (+) of my passive crossover caps (SIT for mid and Stweet only, F5 for the woofer)?
Thanks

Yeah - get somewhat hot after 1 hour of playing Bruce Sprinsteens - The goast of tom joad. The harmonica is such that you can feel it is in the room - never heard anything so close to live-music from a amplifier before.

I have some special heat-sink(for the SIT and some of the other resistors inside. The heat on top hasn`t gotten over 28 deg Celcius - on top of the enclosure. But I must try to measure inside when I return home 1 of june.
And maybe move the SIT to a heat-sink on the back. That will give me better space inside. It got really STUFFED inside. Had a plan about keeping it tidy - but you loose when have a fixed box and have to build according to those confined area.
